ATTACHMENT FOR TYPE-WRITERS.

To all zohom 'itmay concern: 1

Be it known that I, OLIVER V. SOHAUER, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered a certain new and useful Improve-- ment in Attachments for Type-Vvriters, of which improvements the following is a specification.

' The invention described herein relates to certain improvements in billing attachments for type-Writ ers.

It is desirable in sending out statements to keep a copy of the same and it is customaryto make such copies on long sheets. If the statements are short two or more can be copied on the same sheet provided spaces corresponding to the spaces occupied by the printed heading and at the ends of the statements be not left on the long or record sheet.

Thepresent invention has for its object the provision of a suitable stop mechanism whereby the platen of the machine may be turned back after the completion andwithdrawal of each original to such aposition thatthe first line written on a new' bill head inserted after the platen has been turned back will have a certain predetermined position relative to the last line of the previous statement on the record sheet.

The invention is hereinafter more fully ism the position of the parts shown corrc sponding to those of the parts shown in Figs. 3 and 4: Figs. 7 and 8 are sectional views on planes indicatedrespectively by the lines VII-VII and VIII-VIII Fig. 3; Fig. 9 is a plan .view showing the manner of attaching m v spacing mechanism to another form or construction of ty )cwriter; Fig. 10 is a sectional view on a p ane indicat'cd by the line X---,.\" Fig. 9;-Figs. ll; 12, and 13 show trout and sectional elevations Specification of Letters Patent.

and an edge view of a modification of my attachment; Figs. 14, 15, and 16 are similar views of a further modification of the attachment; Figs. 17 and 18 are sectional de tail views of the forinshown in Figs. 14, 15 and 16, Figs. 19 to 22 illustrate diagrammatically the operation of my attach ment in spacing bill heads.

My improvement can be applied with slight modification of the fastening devices to any form of typewriter without any reconstruction or change in the typewriter.

Between two plates 1 and 2 which are secured together but spaced a suitable distance are arranged the pinions 3 and 4 having shafts 5 and (3 supported in bearings formed in openings in the plates 1 and 2. The pinion 3 secured to the shaft 5 is adapted to be driven by the platen shaft and synchronously therewith. In the construction shown in Figs. 1 to 10 this movement of the pinion is attained by connecting the.

shaft 5 to the platen shaft. This can be conveniently done as shown in Fig. 8 by forming a socket 7 on one end of the shaft 5 for the reception of the end of the platen shaft 8, the opposite end of shaft 5 being constructed to engage a socket on the knob 9.

In applying the attachment to the machine, the knob is removed from the shaft 8, the socket 7 secured on said shaft and the knob. 9 fastened on the shaft The backplate. 2 is provided. with one or more arms or brackets adapted to engage the. frame of the machine and hold the controlling attachment in operative position. It will be imderstood the shape and number of supporting arms or brackets will be changed to suit different constructions of machines to which the attachment is applied.

In applying the attachment to an I1. C. Smith & Brother machine, as shown in Figs. 1 and 2 the attachment. is provided with two arms 10 and 11. while for coi-i'necting the attachment to a Smith Premier as shown in Figs. 9 and 10 only one arm 10 is necessary.

It is characteristic of my improvement that after the attachment has been set or adjusted for the required backward movement of the platen for the insertion of the new bill head, only the platen-is moved. There is only one stop employed for arresting the platen and that during a backward movement, the forward movement of the platen is unlimited and a backward movement to the extent for which the attachment is adjusted can be always had without adjusting any of the parts, and a further and .unlimited backward movement can be had by sim 1y shifting a release lever.

Tie backward movement of the platen is determined by a stop movable by the platen and a stop carried on the frame of the at tachment one of said stops being adjustable. In the construction shown the stop 12 on the frame of the attachment is stationary and a stop 13 carried by the spacing disk 14 is adjustable around the same. The disk 14 has when shifteda movement synchronous with and equal to the movement of the platen and is secured on the shaft 6 carrying the pinion 4 which has an indirect driving connection with the platen shaft as shown in Figs. 3 to 8 or a direct connection as shown in Figs. 11 to 16.

In the construction shown in Figs. 3 to '8, the driving connection from the platen to the spacing disk is formed by a pinion 15 carried by a swinging member 16 whereby it is caused to engage the pinions 3 and 6. This frame or member 16 is pivotally mounted preferably on the shaft 6 so that the pinion or idler 15 is constantly in engagement with the pinion 4. A spring 17 is employed to move the pinion or idler toward the pinion 3, but has not sufiicient force to hold the idler in engagement with the pinion 3, when the latter is turned if resistance is applied to the idler 15 or pinion 4 to prevent rotation as hereinafter described. One of the journals of the idler, as 18 extends through curved slot 19 in the plates of the attachment and is engaged by a-hooked finger 20 when the idler is in engagement with pinion ,3 to hold the idler in positive engagement with the pinion. The finger is pivotally mounted and is normally pressed away from the journal 18, and against a cam 21, by the sprin 22. The cam which is carried by the shaft 6 is provided with a notch 23 into which a lug 24 on the finger 20' is forced by the spring. The movement of the finger, when the lug enters the notch releases the journal of the idler and locks the shaft 6 and parts carried thereby as against movement in a direction imparted by the forward movement of the platen. As the shaft 6 and the idler 15 are locked as against rotation by the lug 24, and the idler held in engagement with the pinion 3 only by the spring 17, the platen is free to be rotated forward as when so rotated, the pinion 3 will shift the idler' out of engagement with such pinion.

As before stated the adjustable sto for arresting the backward movement of the platen in connection with the fixed stop may e arranged either on the disk 14 or upon the frame of the attachment. In the construction shown such stop is arranged on the disk 14 and consists of a pin 13 carried by an arm 26 formed on a cap 27 loosely mounted on the projecting end of the shaft 6 as clearly shown in Fig. 7 This shaft is made-hollow and the screw 28 passes through the end of the shaft and engages the top of the cap 27, a spring 29 being interposed between-the head of the screw and the closed' end of the shaft. This sprin serves to push the cap with the pin towar the disk 1.4 and hold the latter in enga ement with perforations a formed around the disk. The spacings of these perforations correspond with the distances between the teeth in the platen spacing mechanism of the machine. This construction affords a convenient means for adjusting the stop 13 to any desired position around the disk.

In Figs. 11, 12 and 13 is shown a modification of my improvement, in which the bill spacing attachment is driven directly from the platen shaft The pinion 3 on said shaft intermeshes directly with the pinion 4 on the shaft 6, which, as shown in Fig. 12 has its journals arranged in slots in the front and back plates of the attachment. On this shaft is also secured a cam 21 having a notch 23 as heretofore described. A lever 30 forked at one end is pivotally mounted in the frame of the attachment, one of said forks being provided with a stop 31 adapted to engage the notch 23 in the cam, a spring 32 connected to the lever tending to shift the same in a direction to cause the stop 31 to enter the notch. The other arm 33 of the lever is adapted to bear against shaft 6 and hold the shaft in a position to positively lock the pinion 4 in engagement with the'pinion fective when the platen is turned backward to insert a bill head and durin a portion of the forward movement of the p aten immediately following the insertion of the bill head.

33 on the lever is shifted out of engagement with the shaft 6 'so that if the pinion 3 be further rotated in'a forward direction the pinion 4 will be forced out of engagement therewith, such movement of the pinion 4 being resisted only by a spring 34 tending to force the pinion 4 into engagement with the pinion 3. A disk 14 carried by the shaft. 6 pal-takes of the motion of such shaft. This disk is provided with perforations a as heretofore described, for the reception of a stop 13 which in this case is formed by a pin inserted in such perforations. The back- Simultaneouswith the locking of the shaft as against such rotation, the arm '3. This positive locking however is only of ward ncrement of the platen during which ofthe machine.

- ()n this shaft are also keyed toothed wheels Ii5. and 36 with which pawls 37 and 38 will engage. The pawls are pivotally mounted upon the spacing disk 14. As the platen is rotated in the feed direction, the shaft will be rotated in the opposite direction, or if an idler be interposed between the two in the same direction as the platen.- The toothed wheel will through the medium of the pawl 37 drag the disk 14 around in the same direction until a shoulder 31) on the-pawl 37 comes into alinement with a notch 23* formed in the inner wall of an annular projection from the plate on the attachment.

, 'lhe pawl is shifted so as to cause the stop or shoulder 39 to enter said notch by a spring +1 and by the engagementof the stop with thisnotch further rotation of the shaft (3 and the'parts carried thereby is checked.

I The movement of' these parts at such time is such aswill he imparted by the platen when rotated fonvard, but when the rotation of the platen is reversed or the latter is turned lmekward, thefirst movement of the shaft will cause thedisk 14 to move therewith by reason of the engagement of the ,pawl 38 carried by the. disk with the. toothed wheel This D'lOYQlllOllt of the disk 1t will draw the pawl 37 alongwith it, the stop 3t) being formed out of the notch 23 by the shape ofthe inner wall ofthe ring 40. The movement of the shaft 6 will continue until the stop pin 13 engages the stationary stop.

In order to permit a free turning back of the platen for the purposes of correction or other purposes, a release is, provided so; that such turning back will not effect or operate the bill spacing device. In the construction shown in Figs. 3 to 8 inclusive, this release consists of a lever 43 pivotally mounted on the. frame of the attachment. and adapted to engage the journal of the idler 15, and shift the same out of engagement with the pinion 3, against the tension of the spring '17. In

the construction shown in Figs. 11 to 13,

the pivot pin 44 of the lever 30 is provided with an eccentric portion 45, 011 which the lever is mounted, and such pin isprovided with an operating handle 46. By turning this pivot 44 the lever 32 will be drawn backward so as to move the arm 33 away from the shaft 6 so that the pinion 4 may on the rotation of the pinion 3, be pushed out of engagement with the latter, and permit a free turning of the platen shaft backward without affecting the attachment.

In the construction shown in Figs. 14 to 18, the pawl 38 is keyed to the pivotal shaft 38 ,'Wh1c'h isloosely mounted in the side plates and such shaft is provided with a turning handle 47. By turning this handle the pawl '38 will be drawn out of engagement with the toothed wheel 36 and that without affecting the pawl 37 which is loosely mounted on the same pivotal shaft;

In Figs. 19 to 22, I have illustrated the manner of operation of my; attachment. Fig. 19 shows a platen, the long record sheet and a bill head with a carbon paper between them. The bill head is completed and ready to be removed from the machine. After the removal of the bill head the platen is turned back until the stop of the disk ld will come in contact with the stationary stop on the frame of the attachment; .The distance or' number of spaces of this backward move ment will of course depend upon the length of the printed matter of the bill head and the distance desired between the adjacent bills or statements. If it is desired to separate the bills by about six spaces, and the. printed matter of the bill head occupies about twenty-four spaces, the operator will in the form of the apparatus shown in Figs.

3 to 8, when the attachment is in the position shown in Fig. t, with the lug of the finger 20 in engagement'with notch 23 of the cam, countback from the first perforation 3 to the left of the stationary stop eighteen spaces and shiftthe cap so astoinsert the pin 26 into that eighteenth perforation.

The parts of the attachment will now occupy relative to such attachment a position corresponding to the printing line of the ma chine. After the completion of the bill head within the machine the bill head isreleased and withdrawn and the platen is turned backward thereby carrying the long sheet and the carbon back eighteen spaces, at which time the stop pin 23 will engage withthe stationary stop of the attachment. A second 'bill is n.ow introduced and the bill moved forward to bring the first printing line of the. new bill head to the printing line of the machine atwhich time the parts of .the machine will occupy the position shown in Fig. 4. I

By reference to Figs. 5 and 6 it will be observed that the idler or transmitting pin.- ion 15 is so arranged with reference to the pinion 3 that when the platen is turned forward the pinion will tend to push the idler or transmitting pinion'15 out of engagement, but when the platen is rotatedbackward, the direct-ion of rotation of the pinion 3 supplements the action of the spring 17 to move the idler into engagementwith the pinion. Y

It will be observed that the. lever 43 is operative only when the idler is unlocked and the pinion 4 locked, and in order that the idler may be unlocked so as to permit the backward movement of the platen at. any time after the stop 13 has moved away from the stop 12 on the forward rotation of the platen and before the finger 20 is released from the cam 21 provision is made by shifting the finger 20 lengthwise. This can be done by forming the pivot pin with an eocentric portion on which the finger will swing. By turning the pin by a handle 51 the finger can be shifted to unlock the idler.
